I'm going to go with what I consider the coming out party. Shane stepped up as an underdog against Corey and imo changed pool. At the same time we had Justin & Chad working with Billy & Grady and that match simply blew everyone away. I believe Mark G was there also and it inspired him to try and take TAR to the next level. TY all.
We started a thread before that match looking for sponsors so we could get commentators. Mark called me and said he would do it and got Grady and Billy to work the match. They hadnt worked together in awhile at that point. Greg Sullivan paid to have a Diamond Table hauled to Sioux Falls for the match. Both of them came to watch the match. About a year later Mark bought out Chuck and Jason and I moved to Vegas to base TAR there.
That was one of the best matches we ever did. It was Shane's coming out party. Technically we had no idea what we were doing. Jason and I were in the basement for weeks trying to figure out how the hell you actually do a streaming PPV. This was 2007 and it wasn't as cut and paste as it is today. Great times.
